我总是得到这个错误，或者＆＃34;没有持久性提供者＆＃34;无论我尝试依赖什么和persistence.xml配置的组合。
这是我的persistence.xml：
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0">
<persistence-unit name="LibraryJPA">
<class>model.Clan</class>
<class>model.Kategorija</class>
<class>model.Knjiga</class>
<class>model.Primerak</class>
<class>model.Zaduzenje</class>
<properties>
<property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/biblioteka"/>
<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
<property name="hibernate.connection.username" value="root"/>
<property name="hibernate.connection.password" value="something"/>
<property name="hibernate.archive.autodetection" value="class"/>
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.format_sql" value="true"/>
<property name="hbm2ddl.auto" value="update"/>
</properties>
</persistence-unit>
</persistence>
这是pom.xml：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

我正在找人帮助我为什么这不起作用，以及我应该如何设置我的pom.xml和persistence.xml以使其工作。
